Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a multi-layer steel plate positioning and support device inside a radiation-proof wall. Background Technology

[0002] Embedded steel plates in radiation shielding walls are a measure to enhance radiation shielding in rooms with large-scale radiological medical equipment in hospitals. Depending on the radiation dose, the required thickness of the steel plates for radiation shielding varies. Considering existing hoisting technology, extra-thick steel plates are vertically segmented and installed in layers.

[0003] According to existing technical solutions, steel plates embedded in concrete walls are positioned and supported using the following two methods:

[0004] (1) Using steel pipes fixed on both sides of the steel plate for diagonal support does not meet the installation conditions of multi-layer steel plates;

[0005] (2) To bolt the steel plate, the steel plate needs to be drilled first, and then a long screw is used to pass through the steel plate and then a nut is used for reinforcement. This incurs additional labor costs and is not economical. Since the steel plate needs to be penetrated during the processing and the penetration direction is parallel to the radiation direction, there is a risk of radiation leakage. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a multi-layer steel plate positioning and support device for the interior of a radiation-proof wall.

Before the lower plate is poured with concrete, the embedded plates 1 are embedded at the installation position of the steel plate. The elevation of the embedded plates 1 is the bottom elevation of the steel plate. During installation, it is ensured to be horizontal, which provides the necessary conditions for the subsequent installation of the support frame to remain vertical.

[0032] An end support 2 is fixedly installed on each of the two embedded plates 1 at both ends. The two end support 2 are arranged opposite each other, and several steel plates 3 are placed between the two end support 2.
